摘要

分别以磺化煤、果壳、PVC塑料、回收旧塑料等4种密度与活性炭相当的惰性填料替代工程上广泛使用的石英砂,结合适当的反冲洗解决复极性固定床电解槽(BPBC,b ipolar packed bed cell)存在的电极污染及填料分层问题.并以含有对硝基酚钠的废水降解实验考察其应用的可行性.结果表明,以回收旧塑料及磺化煤作为填料的BPBC处理效果优于石英砂的,而果壳、PVC塑料的与石英砂的处理效果相当.反冲洗后,以磺化煤、果壳、PVC塑料和回收旧塑料作填料的电解槽再生率均大于石英砂的.

Abstract

Making use of sulphonated coal,fruit hull,plastic of PVC,old plastic in recovery,four kinds of sloth fillers which densities are equal to active carbon to substitute quartz sand which are applied in project extensively.And link with appropriate backwashing to resolve the problem of electrodes pollution and &lamination of the fillers in the bipolar packed bed cell.Then via the treatment of the waste water that contains sodium p-ni-tro-phenolate to investigate the possibility of application.The results are as follow.There are better resuk for the reactors packed with old plastics in recovery and sulphonated coal than the one filled with quartz sand,and the results of the reactors filled with fruit hull and plastics of PVC are equal to it.After backwashing,the regeneration ratio of the reactors filled with sulphonated coal,fruit hull,plastic of PVC and old plastic in recovery are all bigger than the one filled with quartz sand.
